Homemade pumps

[binoculary]

PVC pipe whose diameter is just a bit smaller than that of my hard cock. Sanded the edge rounded and smooth on the cock end. A plastic cap from a can of spray paint happened to exactly fit over the pipe. Drilled a hole in the center of the cap and hot glued a piece of clear plastic tubing. Taped a rubber siphon bulb pump to the other end of the tubing.

Spray a little water into the pipe for lube and sealant, insert cock, let it grow to seal itself inside the pipe, and start squeezing and releasing the bulb. The first squeeze will try to blow the pipe off your cock, so hold it and let the air out. Seal it back up and release the bulb. Now it’s sucking you. If your cock is tight enough inside, you can just repeatedly squeeze and release, and the pipe will slide out and in, moving the skin of your cock as if you were jacking off from the shaft.

I usually have to change hands because the fast repeated squeezing makes my hand tired. Sometimes it will work its way off and the seal will break. At that point my cock is too thick to get back in, but if everything goes right, it has me cumming in a few minutes, feeling like someone else is jacking me off or giving me a blowjob.

A 2nd one is just an aquarium cleaner; the kind that’s just a clear pipe with a hose/tubing connected to one end, and a squeeze pump at the end of that. This makes a decent penis pump, not a masturbator. Although you have to come up with a way to make the open end of the pipe smaller to seal your cock in, because the pipe diameter has to be large enough to allow your cock to plump up from the vacuum. The pump doesn’t seal 100%, so it slowly loses vacuum. Some day I want to buy a brake bleed pump, used for bleeding brake lines, which might have a better seal.

Hey Binoculary, that sounds like an interesting technique you’ve come up with. I was thinking of something similar before I came across a mechanics hand pump. It is already threaded on one end for a quick connect fitting. The 200 cc size is just the right size for my cock. I’m using it for my blow job machine, you can learn more about it and see pics here:
